Continue to feed and dead-head your hanging basket and container plants - they will often keep going until the first frosts.
Try autumn-sowing hardy annuals for bigger plants next year.
Start to divide herbaceous perennials as the weather cools. Make sure you water in the new divisions well.
Fill gaps in borders with autumn flowering plants such as sedum and chrysanthemum to extend the colour to the end of the season.
Plant hyacinth and amaryllis bulbs for forcing, to ensure a crowd of colourful blooms at Christmas.
Plant spring-flowering bulbs such as daffodils, crocus and hyacinths now.
Plant out any biennial plants sown earlier in the year, or if you didn't have time, you can buy plants now. This includes foxgloves, wallflowers and Violas.
September is a good time to plant new perennials as the soil is still warm but there is generally more rainfall.
Keep deadheading annuals, perennials and roses to extend their performance.
Prune climbing roses and rambling roses once they've finished flowering (unless they are repeat-flowering, in which case leave them).
